Compound Poisson approximation for triangular arrays with application to threshold estimation

Abstract


We prove  weak convergence of sums over triangular arrays to the compound Poisson limit using Tikhomirov's method.  The result is applied to statistical estimation of the threshold  parameter in autoregressive models.
